FLUSH HINGE FOR TABLES, DESKS, gcc.

SPECIFICATION forming part of Letters Patent No. 445,532, dated February 3, 1891.

Application led July 25, 1899, Serial No. 359,885. (Model.)

To all whom it may concern:

Be it known that I, JUSTIN BATCHELLER, residing at lVallingford, in the county of Rut land and State of Vermont, have invented certain new and useful Improvements in Hinges, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to hinges, especially hinges for desks, tables, and the like.

The object of the inventionis to produce a hinge which may be applied to the lifting top of a table or desk without projecting above the top, and which will leave but little metal in View at the top; also, to produce a strong hinge of the character referred to which can be applied to a school or other desk with but little cutting away of the wood-work; also, to improve generally the construction of a hinge of the character referred to.

Figure 1 is a side elevation of the hinge as applied to the joint of a desk-top. Figs. 2 and a are sections of the hinge in open and closed position, the sections being on the line wat of the plan, Fig. 3. Fig. 5 is a section through pintle on line .e if, Figs. 1 and 3. Fig. G is a plan, Fig. 7 an elevation, and Fig. 8 an end view, of a hinge with the leaves connected to tongue and socket in the same plane. Fig. 9 is a plan, Fig. 10 a side elevation, and Fig. 11 a section on line g/ y of Figs. 10 and 1l, of a hinge slightly modified from Fig. 1 for attachment at the ends of a desk-lid.

The numeral 1 indicates a flat leaf or plate for attachment to the lowersurface of a desktop by screws passing through holes 2 or in other suitable manner.

The plate 1 has an upwardly-extending socket or mortised projection 3. The plate 1 and socket 3 may be cast integral or may be struck up or bent from a metal plate. Near the front and at the bottom of the socket or mortise there is a cross-bar 4, preferably integral with the socket. rlhe rear end of socket 3 is preferably inclined, as shown at 5, either on a straight or curved line.

The front leaf of the hinge has a flat plate 6, which is attac-hed to the under face of the desk-lid and held by screws passing through holes 7 7 or in other suitable manner. The plate 6 has a tongue 9 projecting upward at a right angle tothe face thereof and of a size to about till the socket or mortise 9 of the other leaf, into which socket the tongue 9 enn ters, and is pivoted by pintle 10, passing through the side plates of the socket and through the tongue. The tongue 9 mayhave a notch 1 l in rear of the pintle and at its lower edge. The tongue 9 turns on the pintle 10 in socket 3 when the desk-cover is lifted, and the bar et serves as a stop to prevent the cover from swinging too far back.

As shown in Figs. 1 to 5, the plate G of the front leaf has a ange turned up along the tongue 9, as at 13. `Then so turned up atan incline relative to plate 6 the flange 13 enters the joint between the desk-top and a cover b, the top a being cut away to receive it. This permits the fastening of the fiange 13 to the desk lid or cover a at the edge by screws passing through holes 14 11i. The fixed topb and lid a of the desk or table top will be jointed on an incline from the perpendicular face of the top, so that the lid will swing up from the pintle 10 as the center of movement without binding in the joint. The fixed top l) will receive the socket 3 in a saw-kerf orsimilarcutting. The lid a will be secured to the leaf 6. The lid may then be swung upward, and the tongues 9, turning on pintles l9,will engage the bar ft of the socket, thus holding the lid up.

The upturned flange 13 of the leaf 6 maybe omitted and the tongue 9 may be continued across said leaf, as at 19, Figs. 6 and 7. In that case the lid a will be cut, as by a saw kerf, to receive the part 19 of the tongue 9.

When applied to the desk the top of socket 3 and of tongue 9 in said socket will be visible from above and should be a plane with the upper surface of the desk-top. No other part of the hinge can be seen and there is no proj ection of the hinge above the desk-top.

The modification shown at Figs. 9, 10, and 11. is for application at the ends of the joint and is like the hinge hereinbefore described, except that the leaves 1 and G are omitted at one side of the tongue and socket. Thus 1X is the base-plate of one leaf, and the socket 3X projects upward from the side instead of the center thereof. The leaf 6 has the tongue 19X at one side thereof and preferably made as thick as the socket 3X, into which the part 9 of the tongue extends. The socket SX is eX- tended to receive a screw-hole 20, and the IOO tongue 19X has a hole 2l. The ends of the desk top and lid are cut out to receive the socket 3X and tongue 19X, respectively. The extension of liange 13X lies in a cut-away space in the lid, in Figs. 1 and 2. The top of tongue 19 and socket 3X Will then show on the top and the sides of said tongue and socket at the end of the desk.

Other lnodiiications may be made within the scope ofmy invention, the general idea of which is that a tongue at a right angle to the plane face of one leaf shall he pivoted in a socket at right angles to the plane face of the other leaf, so that no projection above the top is necessary, and the cut in the top may be narrow like a saw-kerl.

lVhatI claim isl. A flat hinge-leaf having a socket or inortise projection extending at a right angle therefrom and across-bar at the bottom of said socket near the front of the plate, and a second at leaf having a flat-plate tongue at a right angle thereto, said tongue extending into the socket of the first leaf and pivoted about centrally therein, substantially as described.

2. A flat hinge-leaf having e socket extending at a right angle from its plane face and near one end thereof, and a second at leaf having a rigid tongue ata right angle thereto and near one end thereof, said tongue entering the socket aforesaid and pivoted therein, substantially as described.

In testimony whereof I aflix my sign atu re in presence of two witnesses.

JUSTIN BATGHELLER.
